The X4 will inherit the X3's range of 4- and 6-cylinder gasoline and diesel engines along with a 6-speed manual or 7-speed dual-clutch transmission. It is reported the 8-speed Steptronic trans will also be available.

Out on the horizon BMW's M performance division will prepare an X4 M high performance version.

Although, the exterior design has not been finalized, it is believed the X4 will simply be a smaller X6 and maintain the X6's 2-door coupe-like profile.
